(Back to Basics Series 4 of 6) This seminar discusses how to interpret specifications in the area of Electrical Calibration. Specifications apply to instruments, either as sourcing instruments (electrical calibrators) or measurement instrument (digital multimeters). […]
by Chris Grachanen High speed data computations and routing rely on incredibly complex circuit board designs with data transfer rates fast approaching picosecond timing precision (that is one trillionth or one millionth of one millionth […]
by John Dorighi and Rob Sleigh An important consideration for improving the accuracy of time domain reflectometer (TDR) measurements is user calibration. A TDR user calibration is performed to correct for systematic instrument errors along […]
by Jesse Morse If a person making a dc or low frequency measurement fails to select the proper cables, or to properly connect the shields the traceability chain for that measurement can be violated. This […]
By Tom Morgan A method is derived for calculating the resistance tolerances for non-linear resistance scales, whose accuracy tolerances are given in degrees of arc instead of percent of reading or range.
